6 FAQs about [Energy storage capacity ramp-up period]

Why is the excessive ramp period more than 10% BES power capacity?

It should be noticed that in Table 3, the excessive ramp period with 20% BES power capacity is more than that with 10% BES power capacity. This is because of the overly optimistic decision of the simplified ramp-rate limiter without TLOD.

Should PV power output ramp rate be limited to a specific range?

The grid codes developed in China, German, UK and other countries within ENTSO-E framework claim that the ramp rate should be limited to a specific range. For other regional grid codes, there are not any explicit restrictions on PV power output ramp rate at present.

What is storage duration?

Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.

Is ramp capability a problem for load balancing violations?

The growing penetration of generation from renewable energy resources (RESs) has introduced great challenges to the reliable and secure operation of a given power system, among which the scarcity of ramp capability is one of the major concerns for load balancing violations.

Does PV power plant control stabilize ramp rate in PV power station?

The contribution of PV power plant control to stabilising the total ramp rate in PV power station is studied in this section. This subsection studies the PV curtailment for smoothing the output of PV plants in coordination with BES. The BES power capacity is set to 10 MW (20% of PV installed capacity) and rated discharge time is 30 min.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
